音乐表演中的情感表达包括来自音乐家身体动作的重要线索。这个动作与乐谱的执行和传达的情感意图都有关。在这个实验中，一位钢琴家被要求以不同的情感表达意图演奏同一段选段。其目的是验证是否可以通过尝试确定哪些动作线索是最情绪敏感的运动的基础上区分不同的表情。分析是通过一个自动化的系统能够检测两个运动线索的时间配置文件：上半身的运动量和头部运动的速度。结果表明，两者都对情绪表达敏感，尤其是头部运动的速度。此外，一些功能传达信息的运动时间动态变化的表达条件允许情感歧视。这些结果与最近的理论一致，这些理论是情绪表达的动态本质的基础。
EMOTIONAL EXPRESSION IN MUSIC PERFORMANCE includes important cues arising from the body movement of the musician. This movement is related to both the musical score execution and the emotional intention conveyed. In this experiment, a pianist was asked to play the same excerpt with different emotionally expressive intentions. The aim was to verify whether different expressions could be distinguished based on movement by trying to determine which motion cues were most emotion-sensitive. Analyses were performed via an automated system capable of detecting the temporal profiles of two motion cues: the quantity of motion of the upper body and the velocity of head movements. Results showed that both were sensitive to emotional expression, especially the velocity of head movements. Further, some features conveying information about movement temporal dynamics varied among expressive conditions allowing emotion discrimination. These results are in line with recent theories that underlie the dynamic nature of emotional expression.
